PBI-7 is a digital counter of current pulses, which are caused by lightning strikes to the object’s air-termination network. The counter is mounted directly on the lightning down conductor. The PBI-7 is equipped with a display and four control buttons.

By connecting the counter to the down lead of the air-termination network it is possible to get a detailed overview of the number of discharges and their time. Each recorded pulse is provided with a timestamp, by which it can be clearly identified, when the discharge has occurred with an accuracy of seconds.

The PBI-7 is powered by an independent battery pack for easy installation and replacement. The average battery lifetime is 5 years. The advantage of the counter is the battery control system, when the user is continuously informed of the remaining battery capacity. PBI-7 displays the battery cell status value as a figure in the range of 0 to 100 %.

PBI-7 is in compliance with IEC 62561-6: 2018 standard (Requirements for lightning strikes counter LSC).
